To all whom it may concern:

Be it known that I, GoNs'rAN'rnm E. M. TAMBACOPOLO, a subject of the Kin of Greece and a resident of the cit of ew York borough of Manhattan, in t e county and tate of New York, have invented a new and Improved Condenser for Smelterof which the following is a full, clear, an exact description.

The object of the invention is to provide a new and improved condenser for smelter furnace fumes, arranged to insure precipitation of the solid particles and condensation of the metallic and other vapors contained in the smelter fumes with a view to 'revent the" obnoxious 'ases from passing into the atmosphere, at t e same time saving the valuable matter of the fumes.

- For the purpose mentioned, use is made of a conduit, extending from one or a series of smelter furnacesto a stack, the conduit containing successive deflecting'means for deflecting the heavy and coarse solid particles contained in the fumes, a separator for separating the lighter and finer particles of the fumes, and one, or a plurality of washing and reel itating 'devlc'escontaim' ing a suitable iqui for washing the fumes I and 30,

precipitating the valuable matter contains in the fumes.

A practical embodiment of the invention.

is represented in the accompanying drawin s forming a part of this specification, in whic similar characters pf re erence indicate corres onding parts in all the views.

igures 1, 2,3 and 4 are views of successive ortions or sections of the condenser for 'sme ter fumes, Fig. 1 being particularly a side elevation, partly in section, of the beginning end of the condenser connected with a series. of. furnaces, Fig. 2. being a sectional side elevation of the separator, Fig. 3a like view-of the washing and precipitating portion, and Fig. 4 the terminal or stack portion of the condenser.

As illustrated in Fig. 1, a series of smelter furnaces A, Aand A, preferably of coni cal form, discharge their fumes arising from the smelting operations into the beginning end of a section B of a conduit B y providing the u per ends of the smelter furnaces A, A an A with curved outlets A, open forwardly into. the section B. In

"the section B of the conduit B and located between the adjacent outlets A is alrranged a screen 0 foiprecipitating the heavy coarse contained in the fumes passing forward in the conduit B in the direction of the arrows, as lainlyshown in Fi 1; In the bottom of the section B, imm latelyin the rear of a screen C, is formed an opening B normally closed by a hingedtrap door D connected with a chain E extending over guide pulleys E to the outside, to be under the control of an operator for openin or closing the trap door D. Each chain is ada ted to be fastened to a suitable hook E or holding the trap door D in a closed osition. Each opening B opens into an inverted conical'receptacle F arranged between adjacent furnaces, for receiving the heavy and coarse articles deflected by the screen C onto the bottom of the section B, that is, at the o ening B of the trap door D, to allow of lschargin the accumulated particles into the receptac e F on the operator 0 ning the door D periodically (see Fig. lif

In orderto keep the screen C clean, use is made of jets of steam dischar ed from a jet pipe G. located in the rear 0 the screen C an connected with a ipe extending to the-outside of the comiint B and leading to a suitable source of steam supply, The en ply pi e G' is provided with a suitable va' ve Gr or regulating the amount of steam to be sprayed by the ipe G onto the screen C. As in icated in ig. 1, the screen 0 and the jet pipe G are preferably arranged.

obliquely in the section B' of the conduit B to insure roper deflecting of the solid particles wit out hindering the flow of the fumes throu' h the screens. The'rece tacles F are provi ed with suitable doors for periodically cleaning the receptacles of the accumulated contents.

The sectionB' of theconduit B terminates in ,the casin H of a separator provided with a defiec ing partition Hf extending from the top of the casing H to within a short distance of the bottom of the casing, the lower end of the partition H" being fastened to a suitable support H. The casing}! is preferably of brlck h with concrete lining it. As shown'in Fig. 2,'the partition H is curved in such a manner that the incoming fumes strike the up er portion of the partition H and are irected b the same downwardand rearward, to nally pass under thelower. end of the partition H and-into the section B of the. conduit B, and which section B opens into the casing "H a distance above the lower end of the partition H. Now by the fumes coming in contact with the partition H and being whirledar'omid b the same, as indicated by the arrows-in 2, any solid particles contained in 'the"fumes and striking the 5 partition H are-caused to slide down the partition to finally drop into the bottom of the separa toi' Ha accumulate therein. The ca'si H. is provided with suitable doors H gfgaini'ngaccess to the interior of the casing with a view to remove the accumulated contents from'time .to time.

In the entrance and of the section B of the conduit B is arranged an obliquely-dis; posed screen Ito deflect any solidparticles that ma'y'still be contained in the fumes and which solid" articles drop} down into the casing'H. e spraying jet J discharges steam onto the screen I to keep the same clea'n, the jet pi" e J a being connected with a supply pipe having a valve J and similar to the pipe G previousl mentioned. The sectionB' ofthe conduit 7 is provided with an enlargement B containing a suc tion fan K for drawing the fumes out of the casing H. into the section B to propel the fumes forward in this' section, as indicated by the arrows in Fi 2. The suction fan K is driven by a suitable mechanism from a motor, arranged outside of the con- 3o duit B.-' The section. B of the conduit B connects with the section B provided with a number of washing and precipitatin devices L,. L and L, arranged one-in rout of the other and all alike in construction, so that further description of the same is .not deemed necessa Each washing and 'ptrecipitatingdevioe 1s provided with a well into which extends the dependin termmal or angular portion 0 of a cy inder 40 Q fitted within the'section B of the. conduit B, and which section is referably of brick Y b with concrete lining E, as indicated in Fig. 3. The well N is'filled other liquid, and the de' terminates adistance be liquid, as plainly; indicated in Fig.- 3. In the cylinder 0 is mounted to reciprocate a plunger P providedwithvalves p and connected by a lever P with the piston rod Q, of an engine or other motor Q employed for imparting reciprocating motion to the valve plunger Thus when the plunger P moves orward the fumes in front of the plun ,r are forced throu' h the depending mem zr 5 0' into the liqui c nt'ainedin the well N to pass through the ifiuid in an upward drawn into thecylim.

It is understood that by the water emanating from the pi es X, X the fumes are condensed and ot ier valuable, material contained in the same is precipitated and settles in the Base U of the stack '1. Amanhole Sis arran ed to the manh0les% above mentioned. a a

As indicated in F' .8 and 4, the several wells N- as well as t e well formed by the base ,U are in coxnmun'ication with' each other and connected with a well or sump tank N, so that the washing liquid has a in the".sectionB similar level which reaches a pproirimatel up to the I under side of the cylinders 0 an the-washing liquid finall flows into the well N from hich the liqui can be withdrawn for further treatment to recover valuable materials.

The operation is as follows: Whenflthe,

ning, then the fumes passing from the furnaces A,'A and Afli'nto'tlm conduit B are forced forward, and 'thefumes in their forward travel first encounter the screens 0 which deflect the-heavier and coarser particles, and the, fumes in the separator casing are-us rived of their li hter particles andjthe' es are 'subjeo to a series 0 washings in the liquid contained in the wells N andthebaseUtof; the stack U, so that" the fumes finally leaving the stack U are free of obnoxious gases. y p It' will, also be notiedthat by sub'ecting the fumes to theaction of the de acting and washing and precipitating devices all enser 1s in use and the several motors. Q. and W- andthe exhaust. -fan K are runvaluable matter contained in the fumes is saved.
